An account into which someone deposits an equal amount of money at equal periods or equal intervals of time is an annuity.

A predetermined sum of money that you will receive annually for the rest of your life is called an annuity. An annuity is a contract that you have with an insurance provider that calls for regular payments to be made by the insurer to you, either now or in the future.

Certain annuities have payments that are made for a set (limited) amount of time known as the annuity's term. A 30-year mortgage payment is one illustration. With a contingent annuity, payments are made up to a specific occurrence.

As, the deposits have an equal amount with equal intervals.

The measures of the angles are <1 = 85, <2 = 105, <3 = 85 and <4 = 105

The diagram that completes the question is added as an attachment

From the diagram, we have

<1 + <2 = 180 degrees --- supplementary angles

Given that

<2 - <1 = 30 degrees

Add the above equations

So, we have

2<2 = 210

Divide both sides by 2

<2 = 105

Substitute <2 = 105 in <2 - <1 = 30

So, we have

105 - <1 = 30

Evaluate

<1 = 85

Also, we have

<3 = <1

<4 = <2

This means that

<3 = 85

<4 = 105

Hence, the measures of the angles are <1 = 85, <2 = 105, <3 = 85 and <4 = 105

Answer:The answer is -2 over 3

Step-by-step explanation:

Answer:

Yes.

Step-by-step explanation:

4.635 is larger that 4.6135.

The statement which best proves that lines k and m are parallel is: C. Angle 1 is congruent to angle 6 because alternate exterior angles are congruent if two parallel lines are cut by a transversal.

Parallel lines can be defined as two (2) lines that are always the same (equal) distance apart and never meet.

The alternate exterior angle theorem states that when two (2) parallel lines are cut through by a transversal, the alternate exterior angles that are formed are congruent or angles of equal measure.

In this context, we can reasonably infer and logically deduce that the statement which best proves that lines k and m are parallel is angle 1 is congruent to angle 6 because by definition all alternate exterior angles are congruent, if two parallel lines are cut by a transversal.

The equation relating to the total cost and number of students attending the park is $22.5x = y

According to the question we have been given that

Total money paid by Mrs. Jameson = $202.50

Total number of the students = 9

Let the amount of one student to visit the amusement park be X

Thus first we have to find the value of X by following equation,

          9X = $202.50

Solving for X we get,

           X = 202.50/9

           X = $22.5

That is amount for one student is = $22.5

Now we will solve the second part

Let the total cost be represented as y

Let the number of students attending the park be represented as x

Then the equation related to total cost and number of students is given as

                  $22.5x = y

Scale Factor is defined as the ratio of the size of the new image to the size of the old image. The center of dilation is a fixed point in the plane. Based on the scale factor and the center of dilation, the dilation transformation is defined. If the scale factor is more than 1, then the image stretches.

For example, if a square is dilated and the side of the smaller (original) square is 4 units and the side of the dilated square (enlarged) is 12 units, then, in this case, the scale factor will be: 12 ÷ 4 = 3.

Perform a Dilation of 4 on point A (2, 3) which you can see in the picture below. Multiply the coordinates of the original point (2, 3), called the image, by 4. Image's coordinates = (2 * 4, 3 * 4) to get the coordinates of the image (8, 12).

And so if you dilate it with a factor of three, then you're going to want to go three times as far down. So minus three, and three times as far to the left, so you'll go minus six.

The basic formula to find the scale factor of a dilated figure is: Scale factor = Dimension of the new shape ÷ Dimension of the original shape.

The equation of a line perpendicular to y = -10 + 3x that passes through the point (9,2) is y = -1/3x + 1

The equation of the line is given as

y = -10 + 3x

Rewrite the equation as

y = 3x - 10

A linear equation is represented as

y = mx + c

Where

Slope = m

So, we have

m = 3

The slopes of perpendicular lines are opposite reciprocals

This means that

m2 = -1/m1

So, we have

m = -1/3

Evaluate

m = -1/3

The equation of the perpendicular line is then calculated as

y = m(x - x1) + y1

Where

(x1, y1) = (9, -2)

This gives

y = -1/3(x - 9) - 2

Evaluate

y = -1/3x + 3 - 2

Evaluate the sum and the difference

y = -1/3x + 1

So, the equation of a line perpendicular to y = -10 + 3x that passes through the point (9,2) is y = -1/3x + 1

Hence, the required equation of a line perpendicular to y = -10 + 3x that passes through the point (9,2) is y = -1/3x + 1
